Filesystem Hierarchy Standard
/var/spool contains data which is awaiting some kind of later
processing. Data in /var/spool represents work to be done in
the future (by a program, user, or administrator); often data is deleted
after it has been processed.[footnote 38]
The following directories, or symbolic links to directories, must be in /var/spool, if the
corresponding subsystem is installed:
"/var/spool"
lpd
mqueue
news
rwho
uucp
|
"Spool directories"
Printer spool directory (optional)
Outgoing mail queue (optional)
News spool directory (optional)
Rwhod files (optional)
Spool directory for UUCP (optional)
|
Tree 5.14.2.1
The lock file for lpd, lpd.lock, must be placed in
/var/spool/lpd. It is suggested that the lock file for each
printer be placed in the spool directory for that specific printer and
named lock.
"/var/spool/lpd"
<printer>
|
"Printer spool directory"
Spools for a specific printer (optional)
|
Tree 5.14.3.2.2
This directory holds the rwhod information for other systems on
the local net.
BEGIN RATIONALE
Some BSD releases use /var/rwho for this data; given its
historical location in /var/spool on other systems and its
approximate fit to the definition of `spooled' data, this location was
deemed more appropriate.
END RATIONALE
[38] UUCP lock files must be placed in /var/lock. See the above
section on /var/lock.
